In-door and Out-door Plant

So its been getting colder now, so my decision to put my plant inside the apartment has been made.  I begone a new daily routine.  I still have my plant outside when the sun is out, but now when I get home from school or work I move my plant indoors.  Like I mentioned in my last posting; the plant doesn't seem to grow if it it is cold outside.  The plant sits in my kitchen apartment till the next morning when I again place it outdoors.  Things or noticeable actions the plant shows me when the weather is cold; like stunt growth and less water consumption are in advice for a future action in my part.  Seems that after October; if not, during my plant will be spending more; if not, all its time indoors.Growing tomatoes
